I'm still getting to know Eleventy and slowly adding things to the site.
The first order of business was to add a link to my social media account to the
menu bar. The menu bar is powered by the Navigation plugin. According to the
permalink: false to the template will keep a
file from being created in the generated output.
--- eleventyNavigation: key: Label url: https://external-domain.tld order: 4 permalink: false ---
However, as soon as I added the
permalink line, there was an error generating the sitemap.
